Abstract Study aim: This study aimed to determine the knowledge and skills of swimming coaches in providing first aid and cardiopulmonary resuscitation (CPR). Material and methods: The sample consisted of 59 swimming coaches who responded to non-standardized questionnaire. The collected data were processed by the statistical program IBM SPSS (20.0), using the Chi-square test with cross-tabulation, with a level of statistical significance p ≤ 0.05. Results: Obtained data showed a statistically significant difference in the knowledge of swimming coaches about first aid and CPR in relation to coaching experience (p = 0.025); in the knowledge of providing first aid and CPR between coaches who have a certificate of first aid and CPR and those who do not (p = 0.006) and in first aid and CPR knowledge between coaches who have renewed their first aid and CPR knowledge and those who did not (p = 0.045). Conclusion: Based on the findings of the present study, swimming coaches included in this research did not have enough knowledge and skills in first aid and CPR, which makes swimming programs unsafe. By obliging swimming coaches to acquire and constantly improve their knowledge and skills in first aid and CPR, the environment for all swimming programs would become safer.

Background: Missing to detect an ischemic stroke in the emergency department leads to miss acute interventions and treatment with secondary prevention therapy. Our study examined the diagnosis of stroke in the emergency department (ED) and neurology department of an academic teaching hospital. Methods and Materials: A retrospective chart review was performed from March 2017 to March 2018. ED medical document (chart) were reviewed by a stroke neurologist to collect the clinical diagnosis and characteristics of ischemic stroke patients. For determining the cases of misdiagnosed and over diagnosed data, the administrative data codes were compared with the chart adjudicated diagnosis. The adjusted estimate of effect was estimated through testing the significant variables in a multivariable model. The comparisons were done with chi square test. Statistical significance was considered at P < 0.05. Results: Of 861 patients of the study, 54% were males and 43% were females; and the mean age of them was 66.51 ± 15.70. We find no statically significant difference between patient’s Glasgow Coma Scale (GCS) in the emergency department (12.87±3.25) and patients GCS in the neurology department (11.77±5.15). There were 18 (2.2%) overdiagnosed of ischemic stroke, 8 (0.9%) misdiagnosed of ischemic stroke and 36 (4.1%) misdiagnosed of hemorrhagic strokes in the emergency department. Conclusion: There was no significant difference between impression of stroke in the emergency department and diagnosis at the neurology department.

Objectives: The aim of this study was to investigate and compare the level of halitosis in patients with/without fixed crowns and in addition the influence of various crown parameters on halitosis was also explored. Methods: In total, 96 subjects (fixed crowns = 52; no crowns = 44) participated in the study. The levels volatile sulphur compounds (VSCs) of hydrogen sulphide (H2S), methyl mercaptan (CH3SH), and dimethyl sulphide (CH3SCH3) were evaluated with breath samples using gas chromatography and used for classification as presence or absence of halitosis. The periodontal clinical parameters for all the participants as well as the crown parameters for participants with fixed crowns were also evaluated. Cross tabulation, Chi-square test, and one-way analysis of variance tests were used for the statistical analysis and comparisons. Results: Breath samples revealed, 50 (52.1%) participants were suffering from halitosis. Out of VSCs, the level of CH3SCH3 (62.5%) was found to be the most prevalent. Significant correlations were observed between the presence of fixed crowns and oral halitosis (p < 0.001). Statistically significant difference in the concentration of H2S and CH3SH (p < 0.001) and no significance for CH3SCH3 (p = 0.075) between patients with/without fixed crowns was found. The presence of halitosis was more prevalent in the subjects with crown parameters (subgingival margin, over-contoured margin, open-crown margin, over-contoured and under-contoured crowns) considered clinically defective/unacceptable (p < 0.05). Conclusions: Presence of fixed dental crowns significantly contributes to the oral halitosis. Dental crowns with defects significantly impair the hygienic conditions and oral microflora resulting in high prevalence of halitosis.

ABSTRACT Background Human identification is one of the most challenging subjects that man has been confronted with. The fingerprints and DNA comparison are the most commonly used techniques in human identification. Palatoscopy is one of the recently developing methods to identify a victim-based on the palatal rugae pattern. Aims and objectives The aim of the study was to analyze the different rugae pattern in Puducherry population and to find whether palatoscopy is a useful tool in human identification and sex determination. Materials and methods The studies consist of 100 male and female patients between the age group of 20 to 35 years. The rugae pattern was divided assessed based on Kotze classification. Chi-square test and one-way analysis was used to study the statistical significance. Results Wavy pattern appeared to be the most predominant pattern followed by curved, straight, branched and circular pattern in both male and female patients. The shape and number of rugae pattern is similar in male and females. Conclusion The present study concludes that wavy pattern appear to be most common rugae pattern among Puducherry population. No significant difference in rugae pattern was noted among the male and female group. Rugae pattern is unique to each individual and can be an effective tool in human identification.

This study was conducted to investigate the problem of demotivation in English language learning (ELL) within the Moroccan context. To attain this objective, two instruments were adopted: a questionnaire and a writing test. The participants involved in this study were 201 baccalaureate students (second year) from six secondary schools, 84 were males and 117 were females. The data gathered was quantitatively analyzed through frequency distribution and percentages, Cross-tabulation, Chi-Square Tests, Independent Samples t-Test, in addition to the statistical significance which was set at the level of .05 (95%) for all statistical procedures. Six main findings were reported: (1) students positively perceived themselves in ELL; (2) students did not consider English language as a demotivating factor while learning it itself; (3) students were largely positive towards their teachers of English; (4) crowded classrooms were the main demotivators in learning environment among classmates, textbook of English, and classroom atmosphere; (5) generally, learning environment was the main demotivating factor in ELL; (6) as for gender, there was no significant difference between males and females in terms of the number of demotivating factors that they encountered. In the light of these findings, some pertinent implications were provided.

Background: Cardiopulmonary resuscitation is critical in the emergency healthcare settings. Effective cardiopulmonary resuscitation improves the patients’ outcomes hence reducing mortality related to cardiac arrest. The aim of the study was to assess the knowledge and skills of cardiopulmonary resuscitation among health workers at Nakuru County Referral Hospital.Methods: The study adopted an analytic cross-sectional design. A census sampling technique was used to recruit respondents in the study. Questionnaires and checklists were used to collect data.  Chi-square tests and multiple regression analysis were done to determine the significant association between demographic characteristics, knowledge and skills of cardiopulmonary resuscitation.Results: The study found that slightly above half 54.3% (n=88) of the respondents had low knowledge on cardiopulmonary resuscitation. Results revealed that age of respondent (p=0.038) and level of education (p=0.000) were significant. Cross tabulation showed that older respondents (>40 years) and those with a high level of education (degree and or masters) were more two and three times more likely to have a high knowledge of cardiopulmonary resuscitation. The study found out that majority 61.1% (n=99) of the respondents had poor CPR practice. Cross tabulation showed that respondents with high knowledge were four times (OR=4.303) more likely to have good practice.Conclusions: The study concluded that the performance of cardiopulmonary resuscitation is attributable to low CPR knowledge. The study recommends that more emphasis be placed on continuous professional development, and supervision be done after training to ensure that health workers follow the recommended guidelines.

Abstract Introduction Telemedicine is a resource to help limit in-person contacts, which has become increasingly utilized during the Coronavirus pandemic. In the last year, most health care systems have attempted to limit in-person visits in order to help decrease Coronavirus transmission. A retrospective analysis was conducted to determine if the use of telemedicine resulted in an increase in cancellation rates. The data on cancellation rates of a burn clinic using telemedicine was collected for a seven-month period in 2020. The increased rate of cancellations for telemedicine visits compared to in-person visits was found to be statistically significant. Methods A retrospective analysis of patient cancellation rates for 2,463 burn outpatient visits seen in a burn clinic associated with a large tertiary referral burn center was performed covering the time period between April 1st and August 30th of 2020. Cancellations of initial visits for new or recently discharged patients were not included as telemedicine visits were only offered for established burn outpatients. Rescheduling rates for both groups were calculated to assess a potential impact on cancellations. Telemedicine visits consisted of patient encounters conducted by phone or by live video chat. Statistical significance was determined using chi-square test with an accepted p &lt; 0.05. Results The study included 2,463 scheduled outpatient visits comprising 511 telemedicine visits and 1,952 in-person visits. A cancellation rate of 47% occurred for telemedicine visits and a cancellation rate of 40% was observed with in-person visits. Patient visits conducted using telemedicine were associated with a higher cancellation rate (p=0.013). The reschedule rate for telemedicine visits was 22% while in-person visits had a rate of 25% showing no significant association (p = 0.45). Conclusions Telemedicine follow-up visits were found to have an increased rate of cancellations compared to in-person visits. Rates of rescheduling showed no significant difference between groups.

Definition Of

The purpose of the present study was to evaluate the prevalence of teeth malposition (rotated) in Brazilian patients with oral clefts and to contribute to the definition of subphenotypes. This study included 317 patients with nonsyndromic cleft lip with or without cleft palate. Tooth malposition was assessed clinically, through radiographs, and medical history records for each individual. Only teeth malpositions outside the area of the clefts were included. Comparisons were assessed by cross-tabulation and standard chi-square test, and statistical significance was set at p≤0.05. Cleft lip and palate was more prevalent in males, while cleft palate was more common in females. Regarding the presence of tooth malposition, of the 317 patients, 92 (29.02%) had at least one tooth with the dental anomaly. Tooth malposition was more common in patients with cleft lip and palate (16.1%), followed by, respectively, cleft palate (6.9%) and cleft lip (6%) (p=0.112). The highest occurrence of tooth malposition was in the mandible and involved the canines (p<0.01). Few studies have investigated the prevalence of tooth malposition in individuals with nonsyndromic cleft lip with or without cleft palate. Our results confirmed the highest occurrence of dental anomalies, particularly tooth malposition, in patients with oral clefts. Our findings also highlight that there was a higher occurrence of this condition in the mandible and not the maxilla.

Radiographic Mandibular Indices serve as easy and relatively cheap tools for evaluating bone mineralization. Objectives: To examine the effect of age and gender on three mandibular indices: the panoramic mandibular index (PMI), the mandibular ratio (MR) and the mandibular cortical index (MCI), among Libyan population. Methods: The three indices were measured on 317 digital (OPGs) of adult humans (155 males, 162 females). The sample was divided into six age groups (from 18-25 years through 56-65 years). The measurements were analyzed for interactions with age and sex, using SPSS (Statistical Package for Social Studies) software version no. 22. The tests employed were two way ANOVA, the unpaired T-test and chi-square test. Results: The mean PMI fluctuated between 0.37 s.d. 0.012 and 0.38 s.d. 0.012. among the sixth age groups. One-way ANOVA statistical test revealed no significant of age on PMI. On the other hand gender variation has effect on PMI, since independent sample t-test disclosed that the difference between the male and female PMI means statistically significant. ANOVA test showed that the means of MR among age groups showed a negative correlation i.e. MR mean declined from 3.01 in 18-25 age groups to 2.7 in 55-65 age groups. In contrary, the gender showed no effect on MR according two sample t-test at p> 0.05. In regards with MCI, statistical analysis showed that it affected by age that is C1 was decreasing by age while C2 and C3 were increased by age. Using chi square test the result indicated that there is a significant difference among the different age group and the two genders in MCI readings. Conclusion: PMI was influenced significantly by age but minimally by the gender. MR is not affected by gender but has a negative correlation with age. MCI is affected by both age and gender

Abstract Background There is uncertainty surrounding the prognostic value of peritoneal cytology in low-risk endometrial cancer, especially in laparoscopic surgery. The objective of this retrospective study is to determine the prognostic significance of positive peritoneal cytology among patients with low-risk endometrial cancer and to compare it between laparoscopic surgery and conventional laparotomy. Methods From August 2008 to December 2019, all cases of pathologically confirmed stage IA grade 1 or 2 endometrial cancer were reviewed at Osaka Medical College. Statistical analyses used the Chi-square test and the Kaplan–Meier log rank. Results A total of 478 patients were identified: 438 with negative peritoneal cytology (232 who underwent laparotomy and 206 who undertook laparoscopic surgery) and 40 with positive peritoneal cytology (20 who underwent laparotomy and 20 who received laparoscopic surgery). Survival was significantly worse among patients with positive peritoneal cytology compared to patients with negative peritoneal cytology. However, there was no significant difference among patients with negative or positive peritoneal cytology between laparoscopic surgery and laparotomy. Conclusion This retrospective study suggests that, while peritoneal cytology is an independent risk factor in patients with low-risk endometrial cancer, laparoscopic surgery does not influence the survival outcome when compared to laparotomy.
